The U.S Supreme Court says, reversing a one-day-old appeals court ruling that Arizona can enforce its law banning the collection of early-voting ballots by political campaigners.

As per the ruling, it means that in Arizona , the practice that critics call, “ ballot harvesting” will be a felony in Tuesday’s election.

The law has been a tug-of-war between the Republicans and the Democrats, since its enactments earlier this year, as on Friday, when the 9th U.S Circuit Court Of Appealsvoted 6-5 to block the law. Today’s ruling changes that.

Here’s how member station KJZZ in Phoenix explained it on Friday:

“Critics mostly Republicans, call the practice “ballot harvesting” and say it invites voter fraud. Republican lawmakers tried to halt it by passing a state law that made it a felony to turn in someone else’s ballot, with an exception for relatives, caregivers and roommates.

“Democrats sued saying ballot collection is key way to get out the vote, especially from minority households. They argues that the law violated the Voting Rights Act
